“ASIO are really quite alive and alert to these issues…of Australian national security.”

China is our most important trading partner, making a strong relationship vital to Australia’s national interest. But there are growing concerns about covert Chinese actions taking place on Australian soil.

“Every government has an interest in promoting itself abroad to extending its soft power, I guess what’s different about China is the way in which its run through these clandestine operations.”

Five months in the making, this joint Four Corners / Fairfax Media investigation uncovers how China’s Communist Party is secretly infiltrating Australia.

The investigation tracks the activities of Beijing-backed organisations and the efforts made to intimidate opponents of the Chinese Communist party.

“The way the Chinese Government operates is effectively to control and silence dissent.”

And investigates the influence of individuals who have access to political and business leaders.

“Even if they’re not receiving any kind of direction, they would feel some sense of obligation, or indeed make the right impression on the powers that be in China, to demonstrate that they’re being good members of the party, that they’re pursuing the party’s interests.”

The findings will be released in a series of stories through Fairfax Media and ABC platforms, reported by Fairfax’s Nick McKenzie and the ABC’s Chris Uhlmann, culminating in the Four Corners broadcast on Monday night, detailing the full revelations.
